Terrible cheap motherboard

Pros: None, unless you enjoy seeing the blue screen of death

Cons: The computer I built with this board constantly flashes the blue screen of death, even while idling. I've tried reinstalling windows 10 several times and even then the board will blue screen during the install. I've tested every other component of the PC and they all work great.

Other Thoughts: Avoid this motherboard like the plague, and cheap motherboards in general. They're cheap for a reason.

Frustrating

Pros: Honed troubleshooting skills.

Cons: Two boards wouldn't post.

Other Thoughts: Received first board and it wouldn't boot. Used known working video card, power supply, hd, RAM. Removed from chassis, tried different RAM, removed all peripherals, no chassis fans, checked BIOS etc. Figured it was the Mobo, ordered replacement.
Received 2nd board, same problem so I replaced CPU.
Tried replacement CPU, same problem. Looked at reviews of ASRock MoBo's and realized 50% of reviews complained of boards not booting. (Should have looked at reviews before ordering board.) I ordered an ASUS board.
Received ASUS board and installed the same components, it booted and works well. All the time and replacement components wasted, thanks ASRock. Your MoBo's are garbage.

Nice full featured micro ATX mobo

Pros: Like that it has 4 memory slots, most micro ATX have only 2. Nice appearance. Comes with screws for installing NVMe drives, has two M.2 sockets. One is NVMe, one is SATA

Cons: Memory frequency limited to 2400 when all 4 slots are populated

more bsods than you can count severe heat problems

Pros: Cheap

Cons: If there aren’t too many blue screens of death to count then it’s probably over heating. Do not put more than a 4 core processor or it will overheat. Ram needs to be underclocked or undervolted or you will probably overheat. Needs a good power supply and case or you will overheat. You MUST underclock ram, cpu and video card and run fans at max or you WILL overheat. My specs added were ryzen 7 1700, 2x8 GB 2400 ram and a GeForce 1600 GTX. According to CPUID before underclockong was reaching over 100 degree temps. Spend extra money and get a better board. This has been a complete nightmare to the likes I have never had to deal with in my 35 years. Crazy Old Coot has a good video on YouTube about it that’s more in depth

Other Thoughts: Hoping for a refund

For the BSOD issue, please load the BIOS setting default
Test with 1 x memory, switching another memory if it same issue.
For the overheating over 100 degree, please check Celsius or Fahrenheit. If it Fahrenheit that is normal.
If it Celsius that system will be likely to shut down to avoid damage the CPU.
Please try following
Reseat the CPU and re-apply thermal paste accordingly.
Allow better air circulation inside chassis by installing sufficient fans.
